For someone who completely depends on computers for their everyday work, there is no greater disaster than a computer system crashing or a disk collapsing. When you are experiencing disk crashing, your data, files, and other types of data that are saved in your computer drive might be lost. It is important to be aware of preventions and solutions when this situation occurs. You have to know beforehand what to do when your computer system breaks down, especially if you have important contents in your files which you can’t afford to lose. The good news is there are ways to prevent your files or data from permanent deletion.
The solution is called Data Recovery. Recovering lost data may prove to be a complicated and expensive task but there are steps that can be taken done to lessen and minimize the negative impact it brings. Knowing these prevention and recovery steps proves to be very helpful in preserving and recovering your critical files. Using RAID 5 architecture, incorporating physical security and as well as logical security measures to your business/ enterprise information system will help prevent data loss and ease up data recovery.
Using RAID 5 Configurations
Redundant Array of Independent Disks (RAID 5) are configurations that utilizes 2 or more disks in storing mirror images, backups and redundant set of files to ensure that all critical files can still be recovered even if one drive fails.
RAID 1 Configuration
This type of configuration makes use of 2 disks each functioning as storage for files by mirroring. This level of architecture provides fast read and write speed and is effective in today’s modern multi-thread operating systems like Linux or Windows however, recovery is possible only if 1 disk out of the 2 fails. Redundancy in this type of configuration is 100%.
RAID 5 Configuration
The RAID 5 configuration takes advantage of 3 hard drives configured as one however; at least 1 of these drives is used as a backup. This architecture is most effective in higher database applications. One failing drive in RAID 5 architecture will command the backup drive to wake into action making data recovery possible. Performance suffers during read, modify and write of files but efficiency in higher data volume is better.
Both configurations Raid 5 and Raid 1 work best in securing an image or a backup of any file you store in a computer making data recovery possible.
As mentioned earlier, data recovery is a costly process making it worthy to be prevented and avoided at all cost. Information is more important than money in today’s technology driven world and avoiding data loss is always better than paying for the consequences.
Physical Security is often an overlooked aspect in business but losing data due to fire, theft, burglary and other disasters cause real disaster. Some ways of improving physical security is by putting obstacles along the way like multiple locks, firewalls, sprinklers and fence. Placing surveillance and notification systems also helps put more physical security steps in place for your enterprise. How much physical security you need depends largely on the exposure to others your computer system has, how much you trust them and the available budget allocated to this purpose.
Logical security on the other hand guards your files from attackers in the online environment which can cause loss of data. Viruses are a common cause to this. Hackers also take advantage of the Internet to break into a company’s financial information. Logical security can be enhanced by using software that safeguards computers and networks from viruses and human attackers. Some ways of improving logical security includes file encryption, biometric information systems, passwords and authentication.
Both physical security and logical security steps are essential in securing a company’s critical files against loss, theft and permanent damage making data recovery still possible after minor or major disasters.
